Title: Medication carrier and insert therefore
Inventor: WEBSTER JOHN
IPC: A61J7/04
Filed: 1987-10-01
Granted: 1992-12-01
Abstract: ABSTRACT         A medication carrier having a front and rear panel includes four vertical columns of apertures in the front panel and a plurality of dispensing apertures in the rear panel aligning with the front panel apertures.          An insert with corresponding open based pockets carrying medication which can be seen through the walls of the pockets,  is detachably sealed across the open bases of the pockets with  a  frangible membrane and the insert engages  between  the  front  and  rear  panels  with  the pockets  extending  through  the  apertures  in the  front panel.  The areas of each vertical column of apertures in the  panel  and hence  the volume  of  the  corresponding pockets  of  the  insert  vary  according  to  the  average amount of medication taken at various time periods for which each vertical column is designated.  This allows a standard sized carrier to be used for dispensing varying amounts of medication of various sizes thus reducing the need for larger carriers.  Pictorial and written indicia of the various times that the medication should be taken, reduces  the risk of  the wrong  amount  and/or type of medication being taken by the patient.

Title: Plasma deposited coatings and low temperature, plasma method of making same
Inventor: HUDGENS STEPHEN J
IPC: H01L21/205
Filed: 1987-12-04
Granted: 1994-01-04
Abstract: Abstract of the Disclosure A method of depositing a substantially hydrogen free or controlled hydrogen content multi-element alloy film on a substrate.  The method utilizes a microwave excited plasma of a hydrogen free precursor gas to deposit a hard, adherent coating. The method comprises providing a substrate to be coated in a vacuum deposition chamber, with a source of microwave energy coupled to the vacuum deposition chamber.  A substantially hydrogen free reaction gas precursor composition is introduced into the reaction chamber at a pressure corresponding substantially to a pressure minimum of the modified Paschen curve for the reaction gas precursor composition.  Activation of the source of microwave energy excites the reaction gas precursor composition, in this way forming a plasma in the vacuum deposition chamber to deposit a substantially hydrogen free or controlled hydrogen content multi-element alloy film on the substrate.
Patent CA-1280638-C (CA)
Title: Gear pump having conditional dry valve closure structure
Inventor: MCBURNETT JAMES R
IPC: F04B49/02
Filed: 1988-01-27
Granted: 1991-02-26
Abstract: ABSTRACT OF THE DISCLOSURE A dry valve for a gear pump includes a piston having a valve head and a piston head mounted on the opposite ends of a piston rod.  The piston is selectively movable between an opened position, wherein hydraulic fluid is permitted to flow from a reservoir to a pumping chamber of the gear pump, and a closed position, wherein such flow is obstructed.  A source of pressurized air exerts a biasing force against the piston head to selectively move the piston.  An outlet port of the gear pump is connected through a feedback passageway to the dry valve.  The feedback passageway communicates with the side of a chamber in which the piston rod of the dry valve reciprocates between the opened and closed positions.  When the dry valve is in the opened position, the pressurized fluid from the outlet port of the gear pump exerts a side-loading pressure against the piston rod, causing a frictional force to be generated between the piston rod and the piston rod chamber which resists relative movement.  If the frictional force is greater than the biasing force, the source of pressurized air is unable to move the piston to the closed position.  Thus, the dry valve may be moved from the opened position to the closed position only if the pressure of the fluid at the outlet port of the gear pump is less than a predetermined maximum safe magnitude.  After the dry valve is moved to the closed position, a reduced diameter portion of the piston rod is disposed adjacent the feedback passageway.  As a result, fluid is permitted to flow through the feedback passageway and the piston rod chamber to an external drain connected to the reservoir.  This structure returns the lubricating and cooling fluid to the reservoir after circulating once through the gear pump.

Abstract: ABSTRACT OF THE INVENTION     A  transdermal  medication delivery system in which the  medication  is retained in a non-charged form such that  it can be electrically charged.  A d-c electrical current  is  supplied  through  the retained medication when  it  is  in  its  electrically  charged  form  and current  control  is used to control the current level. The  electrical current  supply  circuit,  the control circuit,  the retained charged medication, and the body location  of a patient to which the medication is to be delivered  transdermally,  form  a  closed  loop during operation  so  that  the  current  is  maintained  at a substantially  constant  level while being delivered to the  body location.  Such delivery can be terminated if the current exceeds a maximum allowable level.

Granted: 1993-07-27
Abstract: ABSTRACT OF THE DISCLOSURE     A programmed clock is disclosed for signalling a person the times that dosages of medication are to be taken in compliance with a medication regimen.  A record producing apparatus is provided for producing a record of the person's compliance with the medication regimen.  A control program, including a programmed timer, determines the time that dosages of medication are to be taken from a plurality of compartments.  The program activates the record producing apparatus to provide a message that dosages of medication have been missed and that further actions should be taken in response to the missing of successive dosages of medication.          The control program also activates the record producing apparatus to provide the person with information useful for correlating the actual chemical or brand name identification of the medication with the compartment storing the medication and other information regarding the medication regimen to be taken prior to activation of the timing function.  The control program permits dosages of medication to be taken ahead of schedule while at the same time to disabling the alarm for the scheduled dosage which has been taken ahead of time.  The control program also monitors the external power source to provide a message of when the external power source has been cut off and subsequently resumes and to identify any dosages of medication which were missed during the interval that the external power source was disconnected.  The control program causes the record producing apparatus to print out prior to the scheduled time when scheduled appointments with health care personnel are to occur.  The control program also causes the record producing apparatus to print out prior to taking of the last dosage that it is time to consider the refilling of refillable prescriptions.

Title: Optical fibre with fluorescent additive
Inventor: AINSLIE BENJAMIN J
IPC: C03C4/00
Filed: 1988-10-18
Granted: 1994-03-15
Abstract: ABSTRACT     An optical fibre for use in fibre lasers has the lasing additive, eg Er3+, concentrated in centre of the core.  Preferably the core has an inner region which contains the additive and an outer region which is dopant free.  The concentration of the dopant reduces the pump threshold for a laser and improves the gain performance for a given pump power.  The fibre is conveniently made by MCVD.  The use of Al2O3 in the inner zone appears to reduce loss of dopant during tube collapse.

Title: Slow start power supply
Inventor: PERRY JOSEPH E
IPC: B04B9/10
Filed: 1988-11-23
Granted: 1991-11-26
Abstract: SLOW START POWER SUPPLY Abstract of the Disclosure A slow start motor control circuit for applications wherein extremely accurate speed control is required, such as, in a centrifugal blood separator application is disclosed.  In a blood separator, the degree of separation of cellular components, such as red blood cells and platelets, from the blood plasma is a function of the rotational speed of the centrifuge and the spin time.  The control circuit controls the spin time and the rotational speed of the drive motor by controlling the voltage applied to the motor.  The control circuit allows the drive motor to start relatively slowly to avoid cell breakage which can contaminate the plasma. After the centrifuge attains its desired operational speed, the speed of the motor is regulated and is relatively uninfluenced by ambient temperature variations.
